OBJECTIVE: evaluate the gotten results of the accelerated protocol adapted to the clinic conditions in CLA post operatory patients. METHODS: 30 patients were selected and submitted to an isokynetic test at the pre operatory and 4 months post operatory. RESULTS: the isokinetics evaluations at the pre operatory presented: flexor peak torque 93% at 60°/s and 97,3% at 180°/s. Extensor 87,3% at 60°/s and 94,7% at 180°/s; power of the flexor muscles of 93,3% and extensors of 96,7%; the muscular work of the flexors was of 91,7% and extensors of 90,3%; the flexor peak torque angle was at 28,7°. At the extensor musculature the angle was at 62,2°; flexors eccentric peak torque of 78,3% and the extensors of 12,8%. With 4 months of post operatory the gotten results showed: flexor peak torque 95,4% at 60°/s and 97,1%. at 180°/s; extensor 70% at 60°/s and 75,7%. at 180°/s; power of the flexor muscles of 97,1% and extensors of 79,8%; the muscular work of the flexors was of 94,2% and extensors of 94,2%; flexors eccentric peak torque of 84% and extensors of 24,2%; the flexor peak torque angle was at 27,3°; in extensor musculature the angle was at 61,7°. CONCLUSION: showed that the patients treated with the adapted protocol presented similar results to the original protocol in relation to the muscular conditions.
